Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Differentiate and validate
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

App Store description
Macroscope – Basically turns your iPhone into a Microscope! If you ever wondered how things look up close, Macroscope is the app to answer you that question. From inspecting bugs, flowers to your own skin or something completely random, Macroscope will blow you away in how the close-up world looks like, and to what an iPhone is capable of. Key Features: - Our unique approach to a camera app and our secret focus locking sauce will turn your iPhone into a microscope*. - Zoom ruler from 3x to 15x -> there is no detail we can't capture**. - Privacy focused, we collect no data and only require write access to save Photos. - No in-apps, purchase once keep forever. *) Microscope is a slight exaggeration, you won't be able to replace real world microscopes with this app to see bacteria or other small items. But if you want to see the eyes of a spider, or a hair on a fly, this is definitely close enough! **) Your mileage may vary, depending on lightning and the object you're capturing, colorful objects tend to keep their sharpness much better than those of the same color or smooth surfaces. Pro Tips: - Bring your phone as close as 1,5 fingers distance away from the lens until you start seeing a sharp image. * - Turn on the flashlight even when under direct sunlight for even better sharpness! *) Limited mode is about two palm lengths.

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
